Green vegetables high in vitamin K are among the best foods to include in a balanced diet. Leafy greens such as spinach, kale, collard greens, and Swiss chard can provide substantial amounts of vitamin K, a nutrient your body needs for normal blood clotting and the function of proteins involved in bone health.
The good news is that these vegetables are versatile, affordable, and easy to add to everyday meals. You can enjoy them raw in salads, blend them into smoothies, or cook them in soups, curries, stir-fries, and side dishes.
In this guide, you will discover 15 green vegetables high in vitamin K, compare their approximate nutrient content, and learn simple ways to include them in your diet.
Most Important Points
- Spinach, kale, collard greens, and Swiss chard are particularly rich sources of vitamin K.
- Most green leafy vegetables provide vitamin K1, also known as phylloquinone.
- Cooking changes a vegetable’s volume and serving size, so nutrient amounts per cup can differ between raw and cooked foods.
- Vitamin K supports normal blood clotting and vitamin K-dependent proteins involved in bone metabolism.
- Most healthy adults can meet their vitamin K needs through a varied diet.
- People taking warfarin should keep their vitamin K intake consistent and consult their healthcare professional before making major dietary changes.
Why Are Green Vegetables High in Vitamin K Important?
Vitamin K is a fat-soluble vitamin. It helps activate proteins involved in blood clotting and supports proteins involved in normal bone metabolism.
Green leafy vegetables are especially useful sources of vitamin K1. Including them regularly can help you meet your daily nutritional needs while also providing other nutrients, including folate, fiber, and carotenoids.
According to the U.S. National Institutes of Health, the adequate intake for vitamin K is 120 micrograms (mcg) daily for adult men and 90 mcg for adult women. These are adequate intake values, not Recommended Dietary Allowances (RDAs). Read the NIH vitamin K fact sheet.

How to Add Vitamin K-Rich Green Vegetables to Your Daily Diet
You do not need to eat the same vegetables every day. A simple rotation of leafy greens and other green vegetables can help you enjoy different flavors while meeting your nutritional needs.
Easy meal ideas
- Breakfast: Add spinach to scrambled eggs or an omelet.
- Lunch: Make a romaine, kale, or spinach salad with a light olive-oil dressing.
- Dinner: Serve steamed broccoli, asparagus, or Brussels sprouts with your main meal.
- Soups and curries: Stir collard greens, mustard greens, or spinach into a vegetable soup or curry.
- Snacks and sides: Prepare green beans or cabbage as a simple side dish.
Does cooking reduce vitamin K?
Cooking changes the volume and weight of vegetables, which can make vitamin K appear more concentrated per cup in cooked food. The amount you eat, the cooking method, and the water lost or retained all affect the final amount.
You can enjoy green vegetables raw or cooked. Choose preparation methods you enjoy and can maintain consistently.
Does dietary fat help vitamin K absorption?
Yes. Vitamin K is fat-soluble, so having some dietary fat with your meal can support absorption. For example, add a modest amount of olive oil to a spinach salad or serve vegetables with another food containing healthy fats.
How Much Vitamin K Do You Need Per Day?
The U.S. adequate intake for vitamin K is:
| Group | Daily adequate intake |
|---|---|
| Adult men, 19+ | 120 mcg |
| Adult women, 19+ | 90 mcg |
| Pregnancy, ages 19+ | 90 mcg |
| Breastfeeding, ages 19+ | 90 mcg |
Children and teenagers have different age-based requirements. These figures are adequate intake values, not RDAs.
A serving of spinach, kale, or cooked broccoli can supply a substantial amount of vitamin K. You do not need to hit an exact number at every meal; focus on a varied diet over time.
Important Safety Note: Vitamin K and Warfarin
If you take warfarin, do not suddenly increase or eliminate green vegetables that contain vitamin K. You usually do not need to avoid these nutritious foods, but keeping your intake consistent helps your healthcare professional manage your medication safely.
Talk to your clinician before making major dietary changes or starting vitamin K supplements. This is particularly important if you have a clotting disorder, a condition affecting nutrient absorption, or a medication that interacts with vitamin K.
